srsRAN Docker Build Issue with -DAUTO_DETECT_ISA=False

[Ali78k]

Hiii srsRAN Community,

I'm facing an issue while compiling srsRAN in Docker. On my VM, I resolved an ISA-related error by adding -DAUTO_DETECT_ISA=False to the CMake options, and it worked. However, when I apply the same solution in Docker, the build fails with similar ISA mismatches.

Here's the relevant Dockerfile snippet:

    LIB_UPPER=$(echo $LIB | tr '[:lower:]' '[:upper:]') && \

    -DAUTO_DETECT_ISA=False \  # I've added this line
    -DCMAKE_CXX_FLAGS="-march=native" \  #I've also added this line

Has anyone encountered this before or has any suggestions? Any help would be greatly appreciated.
Best regards,

Additional informaion

In the past, I added -DAUTO_DETECT_ISA=False to srsRAN_Project/.gitlab/ci/builders/builder.sh for the Dockerized version, which resolved the issue. However, the file structure has changed since then.

If I don't add -DAUTO_DETECT_ISA=False, I encounter this error when running the gNB:

srsran_gnb  | --== srsRAN gNB (commit ) ==--
srsran_gnb  | 
srsran_gnb  | 
srsran_gnb  | The PRACH detector will not meet the performance requirements with the configuration {Format 0, ZCZ 0, SCS 1.25kHz, Rx ports 1}.

Hi all,

Just following up on my previous message about the Docker build issue. I also tried changing the GCC and G++ versions from 11 to 10, as well as following the suggestions from this discussion, but the problem persists.

Any additional insights or advice would be greatly appreciated.

Hi all,

I managed to resolve the previous build issue by commenting out two lines in the Dockerfile:

#-DBUILD_TESTS=True \
#-DCMAKE_CXX_FLAGS="-march=${ARCH}" \

However, I'm now facing a new problem when trying to run the gNB with ZMQ. Here’s the error:

srsran_gnb  | --== srsRAN gNB (commit ) ==--
srsran_gnb  | 
srsran_gnb  | The PRACH detector will not meet the performance requirements with the configuration {Format 0, ZCZ 0, SCS 1.25kHz, Rx ports 1}.
srsran_gnb  | Failed to load RF plugin libsrsran_radio_zmq.so: libsrsran_radio_zmq.so: cannot open shared object file: No such file or directory
srsran_gnb  | Factory for radio type zmq not found. Make sure to select a valid type.
srsran_gnb  | srsRAN ERROR: Unable to create radio session.
srsran_gnb exited with code 1

I've noticed that libsrsran_radio_zmq.so cannot be found. I also modified the end of the Dockerfile to use all instead of run for installing dependencies:

RUN /usr/local/etc/install_srsran_dependencies.sh all && \
    /usr/local/etc/install_lib_dependencies.sh run && \
    apt-get autoremove && apt-get clean && rm -rf /var/lib/apt/lists/*

Does anyone have insights into resolving the "radio plugin not found" error or ensuring that ZMQ is properly configured?

Thank you!
Ali
